  div {
    animation-name: sample;

    background-color: blue;
    height: 100px;
    width: 100px;
    position: relative;
  }

  @keyframes sample {
    from {
      left: 150px;
    }
    to {
      left: 0px;
    }
  }
</style>
<body>
  <p>
    Test passes if there is a filled blue square with 'Filler Text',
    which starts staying left for about 2 seconds upon page load,
    then moves from right to left.
  </p>
  <div>Filler Text</div>
  <script>
    var div = document.getElementsByTagName("div");
    div[0].style.animationDuration = "";
    setTimeout(setAnimationDuration, 2000);

    function setAnimationDuration() {
      div[0].style.animationDuration = "10s";
    }
  </script>
</body>
